    New in NSS 3.15.5

    New Functionality

    • Added support for the TLS application layer protocol negotiation (ALPN) extension. Two SSL socket options, SSL_ENABLE_NPN and SSL_ENABLE_ALPN, can be used to control whether NPN or ALPN (or both) should be used for application layer protocol negotiation.
    • Added the TLS padding extension. The extension type value is 35655, which may change when an official extension type value is assigned by IANA. NSS automatically adds the padding extension to ClientHello when necessary.
    • Added a new macro CERT_LIST_TAIL, defined in certt.h, for getting the tail of a CERTCertList.

    Notable Changes in NSS 3.15.5

    • Bug 950129: Improve the OCSP fetching policy when verifying OCSP responses
    • Bug 949060: Validate the iov input argument (an array of PRIOVec structures) of ssl_WriteV (called via PR_Writev). Applications should still take care when converting struct iov to PRIOVec because the iov_len members of the two structures have different types (size_t vs. int). size_t is unsigned and may be larger than int.

    Compatibility

    NSS 3.15.5 shared libraries are backward compatible with all older NSS 3.x shared libraries. A program linked with older NSS 3.x shared libraries will work with NSS 3.15.5 shared libraries without recompiling or relinking. Furthermore, applications that restrict their use of NSS APIs to the functions listed in NSS Public Functions will remain compatible with future versions of the NSS shared libraries.
